Hello, i am trying to get a 4th axis toolpath in Mach3. i made a ring in ArtCAM,i made g-code by using few postprocessors(for mach2,mach3mm,model master4th axis rotary...) but none of them made a rotary toolpath in mach...the g-code contains A axis but on toolpath screen its flat or its not anything like it should look.... anyone can help?thank You???
